A llomey Patented Jan. 3, 1933 UNETED STATES BERNARD H. WEAVER, F HUDSON, NEW YORK AuronA'rrc WIN-now CLOSER Application filed February 27, 1932. Serial No. 595,565.

This invention relates to an automatic window closer, the general object of the inven tion being to provide a sash weighted in such manner as to act to close the sash with clock controlled means for holding the sash in open position until a predetermined time when the clock operated means will permit the weighted window sash to close.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a fragmentary face view of the window showing the invention in use.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 1.

P Fig. 4 is a fragmentary perspective view showing the invention with but a part of the clock mechanism shown.

In this drawing, the letter A indicates the window frame and the letter B the lower sash 0 thereof, and the numeral 1 indicates a number of weights attached to the upper edge of the sash so that the sash will close itself when supporting means which holds it in open position, is removed or released.

I so form the weights that they can be increased or decreased to be adjustable to make the sash properly closed. Blocks 2 of rubber or the like are placed on the sill and act as bumpers for the closing sash and to prevent noise when the sash drops to closed position.

A number of angle brackets 4 are attached to the inner face of one of the side rails of the sash and a lever 5 is pivoted to the side of the frame as shown at 6 with one end adapted to be engaged by any one of these brackets. A second lever 7 is pivoted to the inner face of the frame as shown at 8 with one end adapted to extend over the lever 5 as clearly shown in Fig. 4. A clock G is arranged on the frame and the shaft9 of the alarm mechanism thereof, carries the projection 10 for engagement by the lever 7 as clearly shown in Fig. 4. p

In Fig. 4, one of the projections 10 ofthe shaft 9 extends under an end of the lever 7,

with the other end of the lever extending over an end of the lever 5 and the other end i of the lever 5 is placed under one of the brackets 4, according to the degree the sash is to be opened. Thus the sash is held in open position, against the action of the weight 1, but when the alarm mechanism of the clock starts to operate at the time for which it is set, the projection l0'moves from under the lever 7, and said lever is free to rotate on its pivot, and the weight of the sash upon the lever 5 moves said lever 5 on its pivot, and said lever 5 is free to move as it is not held by the lever 7, and thus the'sash moves down- 7 wa-rdly to closed position.

It will of course be understood that the parts of the clock used for holding the lever 7 against movement must be made strong enough to prevent movement of the lever 7 under the weight of the window.

In order to provide means for adjusting the pivotal point of the lever 5, I provide a number of holes 9 therein as shown in Fig. 2, any one of which may-receive the pivot screw, and as shown, both levers are spaced from the frame by suitable spacers placed on the $0 pivot members.

It is thought from the foregoing description that the advantages and novel features of the invention will be readilyapparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having thus described my invention, what I claim as new is In combination with a window and its sash, weights on the sash for normally holding it in closed position, a vertical row of brackets on one side of the sash, a lever pivoted to aside wall of the window frame and having one end extending under one of the brackets to. hold the sash in raised position, said lever having a longitudinal row of holes therein, anyone of which is adapted to re ceive the pivot, a lever pivoted to the front face of the frame and having one end extending over the opposite end of the first lever, and a detent extending under the opposite end of the second lever.

In testimony whereof I afiix my signature.

BERNARD H. WEAVER.
